Extended Data Fig. 2: The overall cryo-EM maps of SMO–Gi complexes.
From: Sterols in an intramolecular channel of Smoothened mediate Hedgehog signaling
a, The map of SMO–Gi–SAG complex. b, The map of SMO–Gi–24(S),25-EC complex. c, The map of SMOD384R–Gi complex. d, The map of SMOG111C/I496C–Gi complex. Each subunit is displayed in different colors. The α1 and α2 of CRD are labeled and the position of CRD is indicated by red circles.
